摘要: 以H₂WO₄和ZrOCl₂·8H₂O為原料,先采用共沉淀法制備出前驅物,再加熱合成出了ZrW₂O₈粉末.用X射線衍射(XRD)對合成粉末進行物相分析,用掃描電子顯微鏡(SEM)分析粉末形貌,用差熱-熱重分析確定合成溫度.結果表明:溶液pH值控制在2~3范圍內,溶液中Zr⁴⁺和WO₄^2-能同時發生沉淀;所得前驅物在1200℃反應1h,所得產物相主要為ZrW₂O₈,其粒度在100nm左右,且分布均勻.

Abstract: ZrW₂O₈ was economically synthesized from ZrOCl₂·8H₂O and H₂WO₄ through co-precipitation route. The phases of the synthesized powders were analyzed by X-ray diffraction (XRD), the morphology was observed by scanning electron microscopy (SEM), and the synthesized temperature was determined by differential thermal gravimetric analysis. The result reveals that the suitable pH value of co-precipitation of Zr⁴⁺ and WO₄^2- was 2-3. After the precursor was heated at 1200℃ for 1 h, the main phase of the synthesized powders was ZrW₂O₈. The particle size of ZrW₂O₈ powders wad about 100 nm and distributed homogeneously.
